Description
Rated AC voltage is 690, 720, 760, 810 and 850 V (±15 %), and power is 4183, 4365, 4607, 4910 and 5153 kVA at 40 °C and 1500 V DC, respectively by model. The minimum DC voltage for grid operation is 976–1202 V depending on the model. Maximum efficiency is 98.57 %, standby consumption is below 200 W, and current harmonic distortion is below 1 %. Two independent power modules without galvanic isolation connect two separate batteries, which reduces short-circuit currents on the DC side, and short-circuit withstand is 2 × 250 kA for 3 ms. The design is independent of battery technology; lithium-ion, lead-acid or flow batteries can be used. Operation is four-quadrant, with active and reactive power support, operation in weak grids and microgrids with black start, synthetic inertia and grid forming. Cooling is CoolBrid, operating temperature is −20…+60 °C, and altitude up to 2000 m without derating. 50 MW of PCS-E inverters have been supplied to one customer.
How to choose
Choose the model by power and AC voltage. From the 4180E to the 5150E, power at 40 °C and 1500 V DC rises from 4183 to 5153 kVA, and AC voltage from 690 to 850 V. Two separate batteries on two DC buses reduce short-circuit currents and raise system availability. If you need an inverter for a PV plant without storage, see the Proteus PV 4100–4700 up to 4.7 MVA.
